Freemen, also known as Constitutionalists, believe that white Christian males are sovereign citizens beyond the jurisdiction of governmental authority. Freemen have established their own renegade judicial system, known as common-law courts, autonomous townships and their own monetary system, which makes use of fraudulent financial instruments. They derive their beliefs from segments of the Bible, the Magna Carta, Articles of Confederation and the US Constitution. Freemen have been implicated in a variety of offenses ranging from fraud to armed robbery In 1996 a group of Freemen and their followers were engaged in an eighty-one-day stand-off with the FBI in Brussett, Montana. In June 1996 the Freemen peacefully surrendered to the FBI.
